RFR: 8357581: [JVMCI] Add HotSpotProfilingInfo [v2]

[Doug Simon]

> Graal is adding enhanced logic to detect deoptimization cycles and needs to be able to query a method's decompilation counter (i.e. `MethodData::_compiler_counters._nof_decompiles`).
> This PR adds the `HotSpotProfilingInfo` interface so that such HotSpot-specific profiling info can be accessed.
> The change looks bigger in the GitHub review UI than it really is. I have simply renamed the pre-existing `HotSpotProfilingInfo` private class as `HotSpotProfilingInfoImpl` and repurposed the `HotSpotProfilingInfo` name for the *new* public interface.
